Statistical Analysis of Earthquake Risk in the Regions 11 and 12 of Tehran

Despite the vast efforts to determine the earthquake risks at global level, it is not possible yet to forecast exactly when and where it may occur Researches indicated that regarding the available information and statistics, it is possible to anticipate the vulnerability of the residential regions against earthquakes and thus provide the necessary initiatives. To perform this goal, a questionnaire was designed based on the library and field researches. 322 questionnaires were distributed based on the existing population in the regions 11 and 12 of Tehran city, using formulation of Kocaran. The statistical data were analyzed using SPSS software and regression analysis, ^-method correlation, and K square. Some results were obtained such as overcrowding population, effective variables in the rate of vulnerability, and the difference between the average size of the sidewalks in both regions. Moreover, Arc GIS software was used to design the maps and spatial analysis.
